This head is relative with tight lock part end face, link together coaxially, and the diameter of tight lock part is less than the diameter of head.
On this head, there is a screw hole that runs through this head, holding screw is by this screw hole locking nut.
The metope structure that is linked and packed, comprises metope and monolateral dismounting linkage, and this metope comprises a through hole, on the inwall of wherein one end of through hole, has through hole internal thread; This monolateral dismounting linkage comprises screw bolt and nut, wherein nut comprises a head and a tight lock part, head and tight lock part link together coaxially, this tight lock part is tubular structure, comprise inwall and appearance, on inwall, there is internal thread and there is in appearance external screw thread, this internal thread with external thread rotary to contrary; This nut is with the internal thread of tight lock part and the threaded engagement of bolt one end; This nut with the external screw thread of tight lock part and wall and the interlock of through hole internal thread.
This head is relative with tight lock part end face, link together coaxially, and the diameter of tight lock part is less than the diameter of head.
On this head, there is a screw hole that runs through this head, holding screw is fixed on nut check on metope by this screw hole.
The utility model is applicable to the fixed installation of large-scale super scantling metope, this nut has inside and outside twice screw thread, respectively with the threaded engagement of screw thread and the metope through hole of bolt, can allow operating personnel at nut place, carry out the monolateral operation of tightening or unscrewing on one side, save space and manpower, increase work efficiency; On nut, design a holding screw, can prevent that nut from getting loose, improve safety.

Fig. 1 is the monolateral dismounting linkage of the utility model structural representation;
Fig. 2 is the utility model metope and one side dismounting linkage structural representation;
Wherein: 100, monolateral dismounting linkage; 10, bolt; 11, screw thread; 20, nut; 21, head; 211, screw hole; 22, tight lock part; 221, external screw thread; 222, internal thread; 200, metope; 210, through hole; 220, through hole internal thread; 30, holding screw.
[specific embodiment]
Below in conjunction with drawings and Examples, the monolateral dismounting linkage of the utility model is elaborated.
Go out as shown in Figure 1 monolateral dismounting linkage, comprise bolt 10 and nut 20, wherein nut 20 comprises a head 21 and a tight lock part 22, head 21 and tight lock part 22 link together coaxially, this tight lock part 22 is tubular structure, comprise inwall and appearance, have internal thread 222 and have in appearance external screw thread 221 on inwall, this internal thread 222 is contrary with external screw thread 221 rotation directions; This nut is with the internal thread of tight lock part and the threaded engagement of bolt one end.
This head 21 is relative with tight lock part 22 end faces, link together coaxially, and the diameter of tight lock part 22 is less than the diameter of head 21.Head 21 plays to be fixed on treats fixture surface, and lock bolt completes fixing by bolt head and nut.
On this head 21, there is a screw hole 213 that runs through this head 21, holding screw is by this screw hole locking nut.
When actual installation is fixed metope structure, can need metope 200 and monolateral dismounting linkage 100 to coordinate, at metope, process a through hole 210, in this through hole, penetrate bolt 10, one crown of bolt 10 is pressed in one end of through hole, and has through hole internal thread 220 on the inwall of the other end of through hole 210; And bolt in this monolateral dismounting linkage 100 10 is through after through hole 210, coordinates and tighten with nut 20.
This nut 20 comprises a head 21 and a tight lock part 22, head 21 and tight lock part 22 link together coaxially, this tight lock part 22 is tubular structure, comprise inwall and appearance, on inwall, have internal thread 222 and have in appearance external screw thread 221, this internal thread 222 is contrary with external screw thread 221 rotation directions; This nut 20 is with the internal thread 222 of tight lock part 22 and screw thread 11 interlocks of bolt 10 one end; And nut 20 is also with the external screw thread 221 of tight lock part 22 and through hole internal thread 220 interlocks of metope.
On the head 21 of nut 20, there is a screw hole 211 that runs through this head, holding screw 30 is fixed on nut check on metope by this screw hole 211.After nut lockk bolt is fixed on metope, by holding screw 30 locking nuts, prevent that nut from getting loose.
In actual installation is fixing, first bolt is passed to through hole, threaded one at bolt tool of nut sleeve, toward interior rotation, tighten, because the internal thread 222 of tight lock part 22 is contrary with external screw thread 221 rotation directions, when the screw thread along bolt rotates toward tightening direction, for internal thread 222, be to walk toward interlock is more multi-direction, and be also to walk toward the more direction of interlock for external screw thread and through hole internal thread, the dual process screwing like this, and, once bolt skids and does not screw, the external screw thread of nut can make bolt and the further interlock of internal thread toward inward turning is urgent, improve construction validity, increase work efficiency.
The above, it is only the utility model preferred embodiment, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be not depart from technical solutions of the utility model content, according to the utility model technology, refer to any simple modification that above embodiment is done, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
